An inversion is when a gene is flipped.
Deletion ⇒ CGAGGTT = CGTT
A deletion is when a part of gene is deleted.
Duplication ⇒ ATTCGG = ATTCGGATTCGG
A duplication is when a gene is duplicated.
Insertion ⇒ CTTAAT = CTTAACGCT
An insertion is when nucleotide bases are inserted into a gene.
Substitution ⇒ CGAT = CTAT
A substitution is when part of a gene is replaced with a different base pair.

A syringe with 32.0 mL contains gas at 649.0 mmHg. The plunger is pushed in and now the volume is 19.5 mL. What is the new pressure?
Answers
Answer:
1.40 atm
Explanation:
P1V1 = P2V2
P2= P1* V1/V2
P1=649.0mmHg
V1= 32.0mL
V2= 19.5mL
P2=649.0mmHg*32.0ml/19.5ml=
1065.03mmHg
To get mmHg to atm. The formula is 1atm/760mmHg
Use the answer you got in mmHg to convert into (atm), If you were asked
1065.03mmHg*(1atm/760mmHg)= 1.40atm

Find the mass of silver chloride formed if
(a) 20 cm of 2.5 mol/dm^3 of magnesium chloride solution is used.
(6) 20 cm of 2.5 g/dm^3 of magnesium chloride solution is used.
Answers
a. 1,4332 g
b. 7.54~g
Further explanationGiven
Reaction
MgCl2 (s) + 2 AgNO3 (aq) → Mg(NO3)2 (aq) + 2 AgCl (s)
20 cm of 2.5 mol/dm^3 of MgCl2
20 cm of 2.5 g/dm^3 of MgCl2
Required
the mass of silver chloride - AgCl
Solution
a. mol MgCl2 :
[tex]\tt 20~cm^3=20\times 10^{-3}~dm^3\\\\mol=M\times V\\\\mol=2.5~mol/dm^3\times 20\times 10^{-3}DM^3=0.05[/tex]
From equation, mol AgCl = 2 x mol MgCl2=2 x 0.05=0.1
mass AgCl(MW=143,32 g/mol)= 0.1 x 143,32=1,4332 g
b. mol MgCl2 (MW=95.211 /mol):
[tex]\tt mol=M\times V\\\\mol=\dfrac{2.5~g/dm^3}{95,211 g/mol}=0.0263~mol/dm^3[/tex]
From equation, mol AgCl = 2 x mol MgCl2=2 x 0.0263=0.0526
mass AgCl(MW=143,32 g/mol)= 0.0526 x 143,32=7.54~g

C. 2x (6.02x10^23)g
D.15.99 x (6.02x10^23)g
Answers
Answer:
D
Explanation:
We already know oxygen's mass is 15.99 amu, and the mass of a mole is 6.02 * 10^23, so just multiply the two together for 15.99 * (6.02 * 10^23) g.
15.99 x (6.02x[tex]10^{23}[/tex])g mass does 1 mol of O2 gas have. Hence, option D is correct.
What are moles?A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

A 488.3 gram sample of an unknown substance (MM = 92.41 g/mol) is heated from -23.1 °C to 51.8 °C. (heat capacity of solid = 2.96 J/g･°C; heat capacity of liquid = 1.75 J/g･°C; ∆Hfus = 8.04 kJ/mol; Tfinal = 17.6 °C) a)How much energy (in kJ) is absorbed/released to heat the solid? b)How much energy (in kJ) is absorbed/released to melt the solid? c)How much energy (in kJ) is absorbed/released to heat the liquid? d)What is the total amount of energy that must be absorbed/released for the entire process?
Answers
Answer:
a) The heat energy absorbed to heat the solid is approximately 58.8 kJ
b) The heat required to melt the solid is approximately 3.93 kJ
c) The heat required to heat the liquid is approximately 29.2 kJ
d) The total amount of energy, absorbed in the entire process is approximately 92 kJ
Explanation:
a) The given parameters are;
The mass of the substance = 488.3 grams
The molar mass of the sample = 92.41g/mol
The temperature change of the substance = -23.1°C to 51.8 °C
The heat capacity of the solid substance = 2.96 J/(g·°C)
The heat capacity of the liquid substance = 1.75 J/(g·°C)
ΔHfus = 8.04 kJ/mol
Taking the melting point temperature of the solid as Tfinal = 17.6 °C, we have;
The heat energy absorbed to heat the solid, Q₁ = 488.3 × 2.96 × (17.6 - (-23.1)) = 58826.4776 J ≈ 58.8 kJ
b) The heat required to melt the solid, Q₂ = ΔHfus × m = 8.04 × 488.3 = 3925.932 J ≈ 3.93 kJ
c) The heat required to heat the liquid, Q₃ = Mass × The specific heat capacity of the liquid × The change in temperature
Therefore;
Q₃ = 488.3 × 1.75 × (51.8 - 17.6) = 29224.755 J ≈ 29.2 kJ
d) The total amount of energy, absorbed in the entire process, ΔQ, is given as follows;
ΔQ = Q₁ + Q₂ + Q₃ = 58826.4776 J + 3925.932 J + 29224.755 J = 91,977.1646 J ≈ 92 kJ

Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:
[tex]\tt \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }[/tex]
r₁=5gm/30 min
M₁=molar weight of H₂-hydrogen= 2 g/mol
M₂=molar weight of SO₂-sulfur dioxide= 64 g/mol
[tex]\tt \dfrac{5/30}{r_2}=\sqrt{\dfrac{64}{2} }\\\\\dfrac{5/30}{r_2}=4\sqrt{2}\\\\\dfrac{5}{30}=r_2.4\sqrt{2}\\\\r_2=\dfrac{5}{30\times 4\sqrt{2} }=\dfrac{\sqrt{2} }{48}[/tex]
the time required (for the same amount=5 gm) :

In an atom model, the first energy level can hold _____ electrons, the second level can hold _____ electrons, and the third level can hold _____ electrons.
Answers
Answer:
In an atom model, the first energy level can hold 2 electrons, the second level can hold 8 electrons, and the third level can hold 18 electrons.
Explanation:
The Electronic Configuration of the elements is the arrangement of all electrons of an element in energy levels and sub-levels (orbitals).
There are 7 energy levels, numbered from 1 to 7, and in which electrons are distributed, logically in order according to their energy level. Electrons with less energy will be spinning at level 1. Each level is divided into sub-levels. These sub-levels into which each level is divided can be up to 4. These 4 sub-levels are called: s, p, d, f. In the sub-level s there can only be a maximum of 2 electrons, in p there can be a maximum of 6 electrons, in the sub-level d 10 electrons and finally in the sub-level f there can be a maximum of 14 electrons.
In level 1 there is only one sub-level, which will be the s. In level 2 there are 2 sub-levels, the s and the p. At level 3 there are 3 sub-levels s, p and d. And at level 4 there are 4 sub-levels, the s, the p, the d and the f.
Then, in an atom model, the first energy level can hold 2 electrons, the second level can hold 8 electrons, and the third level can hold 18 electrons.

Answers
Answer:
a) 1.65 bar
b) 4.2 L
Explanation:
From Boyle's law(since temperature is constant);
P1V1= P2V2
P2 = P1V1/V2
V1 = 110 ml
T1= 33 + 273 =306 K
P1 = 2.4 bar
V2 = 160 ml
T2 = 33 + 273 = 306
P2 =?
P2 = 2.4 * 110/160
P2 = 1.65 bar
2)
T1 = 26.2 + 273 = 299.2 K
V1 = 4L
T2 = 38.1 + 273 = 311.1
V2 =?
From Charles's law;
V1/T1 = V2/T2
V1T2 = V2T1
V2 = V1T2/T1
V2 = 4 * 311.1/299.2
V2 = 4.2 L
